k well each line, box, and row must have 1 of each number in it…and that’s pretty much it…but the number can’t be done in a line, box, or row more than once

It depends upon which version you are playing…
I will explain for standard Sudoku…
In standard Sudoku there are 9 boxes across and 9 boxes up/down.. AND there are 9 groups of 9 boxes (usually marked out with darker borders around a 3×3 set…
for each row (across) and each column (up/down) AND for each group (the group of 3×3 boxes) there can be only 1 of each number from 1 to 9 and so there HAS to be 1 of each…
If you pick out an easy puzzle (1 star in some books) they will fill in a lot of the boxes for you and if you look across any row the numbers that are given in that row cannot be used again in the same row.. same with columns and Groups…
I usually start by looking at Groups (the 3×3 block groups.. they divide up the puzzle like tic-tac-toe with a group of 9 boxes inside each place where you would put an x or an o…
Find out where there is a number in the top row, and the same number in the 2nd or 3rd row (they will be in different Groups).. now in the last of the 3 groups across.. look to see if the available (available to put that number into) row has 2 numbers already filled in.. if so then the empty spot has to hold the number…
Example: below, look at the 2nd and 3rd rows.. and see that you can find a “2″ in each of them. There is no “2″ in the left Group, but there is a “2″ in the 3rd row of the second Group and a “2″ in the 2nd row of the third Group (hard to draw in this answer format).. in this case the ONLY empty spot in the First Group is in the first row and second column.. and that is where the “2″ goes…
1. 3.. 456.. 789
456.. 789.. 123
789.. 123.. 456
Notice, I have only shown the top row of Groups (3 blocks of 3×3 boxes) each with the numbers from 1 to 9 in them.. each row has 1 to 9 and each column Would have 1 to 9 in it (the full columns are not shown)…
you can find Soduko puzzles online and some of them have “help” where they will give you hints.

the numbers have to go 1-9 (in a 9×9 square) in each row, column, and each separate square.

The idea behind the game is to use the numbers only once in each row, each column and each set of the 3×3 boxes. The nine boxes are set up three rows and three columns.
Start with the numbers in the top three boxes. Take a look at what numbers are already repeated. For example, if box set #1 has a 9 in the third row, and box #3 has a 9 in row two, look to see where the 9 can go in box #2, row one.
You do this by looking down at the columns and seeing if the 9 is shown in either column (for example, if a nine is in the box set below in column 1 and the box below it has a nine in column three, then the only place a nine can go is row one, column two. Repeat for each number.
Once you’ve done the boxes, use the same logic for each row, one by one, and then each column, one by one. If you fill in a number, use the above logic to try to see if you can fill in a number in another box set.
It’s a tough game to get, but once you do it’s fun.
One great explanation I’ve found is:

The numbers cannot repeat itself horizontally, diagonally or within a box. The easiest way that I do is to look at the top 3 boxes and see which number have been given 2 times. For example. If there is a number 2 on the top row and a number 2 in the middle row then you know that number 3 must be somewhere in the 3rd row. am i confusing you?? So you look in which box there is no 2 then put it in there….. hope that helps….

Wikipedia has a few good ways to solve Sudoku games:
For easier games I like to use scanning through the blocks and lines to see what matches up. It is a good way to get started and to get an eye for the numbers
